I am privileged to have a couple of adult students , the husband over 80, and the wife almost eighty. They go walking before they make use of the gold card to ride the free bus. They also go to swim and the sauna to keeep warm.

She uses a pencil, and doesn't use reading glasses. She did tell me she has macular degeneration.
